Thermally stabilized fastener system and method

ABSTRACT

A thermally stabilized fastener system and method is disclosed. The disclosed system/method integrates a fastener (FAS) incorporating a faster retention head (FRH), fastener retention body (FRB), and fastener retention tip (FRT) to couple a mechanical member stack (MMS) in a thermally stabilized fashion using a fastener retention receiver (FRR). The MMS includes a temperature compensating member (TCM), a first retention member (FRM), and an optional second retention member (SRM). The TCM is constructed using a tailored thermal expansion coefficient (TTC) that permits the TCM to compensate for the thermal expansion characteristics of the FAS, FRM, and SRM such that the force applied by the FRH and FRR portions of the FAS to the MMS is tailored to a specific temperature force profile (TFP) over changes in MMS/FAS temperature. The TCM may be selected with a TTC to achieve a uniform TFP over changes in MMS/FAS temperature.

FIELD OF THE INVENTION

The present invention relate to the product of and systems and methods for generating mechanical fastening systems that are thermally stabilized (“athermalized”) over a wide temperature range. Without limitation, the present invention may be applied to situations where a plurality of components in a mechanical system must be constructed in a manner so as to maintain constant distances, tensions, or compressions along a common mechanical axis (CMA).

PRIOR ART AND BACKGROUND OF THE INVENTION Standards Literature References

This patent application includes by reference the standards literature publication document SAE AIR1754B Aerospace Information Report for “Washer, Thermal Compensating, Metric Series” from SAE International (www.sae.org), Issued 1981-December, Revised 2001-October, Reaffirmed 2012-October, Stabilized 2019-February, Superseding AIR1754A. SAE states in this document a rationale that: “This document has been determined to contain basic and stable technology which is not dynamic in nature.” SAE provides a STABILIZED NOTICE in this document that reads: “This document has been declared ‘Stabilized’ by the SAE E-25 General Standards for Aerospace and Propulsion Systems Committee and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability of technical requirements. Newer technology may exist.”

This document, first issued in December 1981, details the use of thermally compensating washers and details the use of conventional A286, INCONEL 903, WASPALOY, Invar, or other materials known in the art to accomplish thermal compensation. Since this document was stabilized in February 2019 (38 years after first issuance) as of this date the document indicates that were no known methodologies of achieving thermally stabilized fasteners other than that provided in this SAE standard. As such, the present invention as described herein is novel with respect to the disclosure scope of this SAE document.

Long-Felt Industry Need for Thermally Stabilized Fasteners

All metals expand when hot and contract when cold. The positive thermal coefficient experienced by most metals can have a huge impact on industrial, aerospace, defense, or commercial applications that see deterioration in the performance, efficiency, and safety of their products due to severe temperature swings and/or vibration. For example, when cooled, aluminum shrinks significantly while a steel bolt shrinks to a lesser extent and as such a fastener joining these materials will loosen with decreasing temperature. When the same joint is heated, the aluminum expands more than the steel bolt and the joint can become over tight stretching or even breaking the bolt. This loosening during thermal cycling and vibration cause fatigue and bolt failure, a long standing major problem in a variety of industries. Specifically, this loosening causes problems for seals, gaskets, pumps, satellites, optics, precision equipment, automobiles, and autonomous vehicles that see performance reduction and equipment failures that cause safety concerns.

The present invention teaches the use of thermally compensating members (TCM) such as washers and other metallic forms to completely change the way engineers attack the thermal expansion problem all together. Using a simple temperature compensating metal washer that expands when cooled can take up the slack in a fastener joint and stabilize the clamping force of bolts used in this wide array of applications. By reacting opposite to other metals, it can keep a pump's bolting from coming loose, hold satellite components in place during launch and throughout the severe temperature swings in space, and maintain constant load on cryogenic assemblies found in multiple processing environments like liquefied natural gas (LNG) and scientific research labs.

The present invention allows engineers and designers in the aerospace industry to implement more reliable fastening solutions. This allows a reduction in the high cost of system failure associated with current fasteners that degrade over time due to loosening or over-tightening during large temperature swings. By offering a simple, passive solution to the age-old problem of thermal expansion in metals, the potential economic impact is significant, as these temperature stabilized fasteners allow engineers and scientists to do things they have never done before, all the while seeing reduced costs in maintenance programs, improved reliability, enhanced safety, and far better performance and efficiency in their product.

Commonly used solutions for battling changes in fastener load include: (1) building everything out of one material and (2) using split, wave spring, or Belleville washers. Unfortunately, using a single material locks engineers into unrealistic material property requirements. For example, while aluminum bolts would solve the aluminum fastening problem, they do not work well due to their low hardness, strength, and elastic modulus. Additionally, split, wave, and Belleville washers have limited utility under normal bolt loading conditions. John H. Bickford [1] describes these types of washers as being, “of questionable value,” because, “their stiffness . . . is so much less than that of most fasteners.” Richard T. Barrett in the NASA Fastener Design Manual [2] also states, “the washer is normally flat by the time the bolt is fully torqued” and concludes, “a lock washer of this type is useless for locking.” These assertions have been echoed by others in the industry that describe how they just put them in and, “hope for the best.” It would seem that the industry has a long-felt need to solve this fastener problem regarding thermal expansion issues in manufacturing.

Deficiencies in the Prior Art

Prior art thermally stabilized fastener systems typically suffer from the following characteristic deficiencies:

-   -   Prior thermally stabilized fastener systems have a coefficient         of thermal expansion (CTE) that cannot accurately be controlled.     -   Prior thermally stabilized fastener systems have a coefficient         of thermal expansion (CTE) that cannot be controlled across one         or more axes of expansion.     -   Prior thermally stabilized fastener systems have a coefficient         of thermal expansion (CTE) that cannot be tailored to provide a         customized expansion coefficient across one or more axes of         expansion.     -   Prior thermally stabilized fastener systems have a coefficient         of thermal expansion (CTE) that cannot be tailored to provide a         customized clamping load with temperature changes across one or         more axes of expansion.     -   Prior thermally stabilized fastener systems cannot provide a         zero coefficient of thermal expansion (CTE) over one or more         axes of expansion.     -   Prior thermally stabilized fastener systems cannot provide a         negative coefficient of thermal expansion (CTE) over one or more         axes of expansion.         To date the prior art has not fully addressed these         deficiencies.

OBJECTIVES OF THE INVENTION

Accordingly, the objectives of the present invention are (among others) to circumvent the deficiencies in the prior art and affect the following objectives:

-   -   (1) Provide for a thermally stabilized fastener system/method         for producing same that have a coefficient of thermal expansion         (CTE) that can accurately be controlled.     -   (2) Provide for a thermally stabilized fastener system/method         for producing same in which the coefficient of thermal expansion         (CTE) can be controlled across one or more axes of expansion.     -   (3) Provide for a thermally stabilized fastener system/method         for producing same in which the coefficient of thermal expansion         (CTE) can be tailored to provide a customized expansion         coefficient across one or more axes of expansion.     -   (4) Provide for a thermally stabilized fastener system/method         for producing the same in which the coefficient of thermal         expansion (CTE) can be tailored to provide a customized clamping         load with temperature changes across one or more axes of         expansion.     -   (5) Provide for a thermally stabilized fastener system/method         for producing same that can produce a zero coefficient of         thermal expansion (CTE) across one or more axes of expansion.     -   (6) Provide for a thermally stabilized fastener system/method         for producing same that can produce a negative coefficient of         thermal expansion (CTE) across one or more axes of expansion.

While these objectives should not be understood to limit the teachings of the present invention, in general these objectives are achieved in part or in whole by the disclosed invention that is discussed in the following sections. One skilled in the art will no doubt be able to select aspects of the present invention as disclosed to affect any combination of the objectives described above.

BRIEF SUMMARY OF THE INVENTION

While all metals expand when hot and contract when cold, the recent development of tailored thermal expansion coefficient (TEC) materials allows the creation of metallic materials that do the opposite: they contract when heated and expand when cooled. This brand-new material property enables the creation of fasteners that compensate for the natural expansion and contraction of other materials being fastened and thus the creation of thermally stabilized fasteners as described herein.

The present invention generally addresses the need for thermally stabilized fastener systems having a known coefficient of thermal expansion (CTE) in the following manner. The use of a conventional fastener (FAS) and fastener retention receiver (FRR) that fix a first retention member (FRM) and/or a second retention member (SRM) is augmented via the use of a tailored temperature compensating member (TCM) along the mechanical fixation axis (MFA) of the FAS/FRR/FRM/SRM combination that has a thermal characteristic that complements that of the FAS/FRR/FRM/SRM thermal expansion characteristics. By properly fabricating the TCM to complement the thermal expansion and mechanical characteristics of the overall FAS/TCM/FRR/FRM/SRM combination mechanical fastener system, the mechanical load is made constant and thermally invariant. In some circumstances the FAS and/or FRR may be constructed of CTE material in this thermally stabilized fastener (TSF) configuration.

However, it should be understood that this embodiment is only one example of the many advantageous uses of the innovative teachings herein. In general, statements made in the specification of the present application do not necessarily limit any of the various claimed inventions. Moreover, some statements may apply to some inventive features but not to others.

Tailored Thermal Expansion Coefficient (TEC) Defined

The term “tailored thermal expansion coefficient (TEC)” as used herein to describe the formulation and manufacture of the temperature compensating member (TCM) refers to the methods and products of material manufacture described in United States Utility Patent Applications that are included by reference in this patent application.

These patent applications teach the fabrication of metallic materials that have a range of tailored thermal expansion coefficients that are outside of those available using conventional A286, INCONEL 903, WASPALOY, Invar, or other materials known to those of skill in the art as described in the prior art included-by-reference document SAE AIR1754B Aerospace Information Report for “Washer, Thermal Compensating, Metric Series” from SAE International (www.sae.org), Issued 1981-December, Revised 2001-October, Reaffirmed 2012-October, Stabilized 2019-February, Superseding AIR1754A. Since this document was stabilized in February 2019 (38 years after first issuance) as of this date the document indicates that were no known methodologies of achieving thermally stabilized fasteners other than that provided in this SAE standard. As such, the present invention as described herein is novel with respect to the disclosure scope of this SAE document.

Mechanical Member Stack (MMS) Form Not Limitive

The present invention will be described generally in terms of a mechanical member stack (MMS) having several mechanical layers. These layers will be presented visually for purposes of illustration only, and the specific form of each layer is not limited by these visualizations. The mechanical member stack (MMS) may take many physical forms, many of which are not depicted herein but will be readily known by one of ordinary skill in the art.

Mechanical Member Stack (MMS) Sequence not Limitive

The present invention will be described generally in terms of a mechanical member stack (MMS) having several mechanical layers. These layers will be presented visually for purposes of illustration only, and the specific sequence or order of each layer is not limited by these visualizations. The mechanical member stack (MMS) may take many sequenced physical forms, many of which are not depicted herein but will be readily known by one of ordinary skill in the art.

Fastener (FAS) may be TCM not Limitive

The present invention will be described generally in terms of a fastener (FAS) in conjunction with a MMS having several mechanical layers. While the MMS is shown herein as incorporating a temperature compensating member (TCM), the fastener (FAS) may incorporate a TCM characteristic as well. In a similar way that the fastener retention receiver (FRR) shown herein can incorporate a TCM characteristic, the fastener (FAS) may also be temperature compensating. This TCM characteristic may be in lieu of or in addition to a TCM within the MMS.

Fastener (FAS) not Limitive

The present invention will be described generally in terms of a fastener (FAS) in conjunction with a MMS having several mechanical layers. The fastener will be presented visually for purposes of illustration only, and the specific form of the fastener is not limited by these visualizations. While bolts, cap screws, socket head cap screws, and a variety of rivet configurations are typically used as fasteners and may be shown herein, the term “fastener” should be interpreted generally and not limited to these forms.

Fastener Retention Receiver (FRR) not Limitive

The present invention will be described generally in terms of a fastener retention receiver (FRR) in conjunction with a MMS having several mechanical layers. The fastener retention receiver (FRR) will be presented visually for purposes of illustration only, and the specific form of the fastener retention receiver (FRR) is not limited by these visualizations. While hexagonal nuts are typically used as fastener retention receiver (FRR) and may be shown herein, the term “fastener retention receiver (FRR)” should be interpreted generally and not limited to these forms. Furthermore, in some preferred exemplary embodiments that make use of rivet fasteners, the FRR may be integrated with the function of the fastener retention tip (FRT) such that the use of riveting tools to deform the FRT serve as the function of the FRR to secure the FAS to the MMS. Thus, mention of the FRR should include the anticipated possibility that the FRR is integrated with the FRT and is not a separate component of the overall fastener system.

Multi-Member TSF Exemplary Embodiments

The present invention may best be described in terms of several multi-member exemplary embodiments in which a temperature compensating member (TCM) is utilized in conjunction with other members of a mechanical fastener assembly to achieve an thermally stabilized fastener (TSF) having desired degree of thermal stability. The discussion below is not limitive of the scope of the claimed invention, but rather provides several concrete examples of the invention teachings as applied to several common application contexts.

MMS Aperture not Limitive

The MMS as described herein includes passages or apertures through which the FRB of the FAS is passes through the MMS. While the FRH and the FRR are configured to mechanically couple elements within the MMS via the FRB and these apertures, the present invention makes no limitation as to the physical form of these apertures.

TCM Form not Limitive

While the present invention may be described in some embodiments using a TCM having a washer form factor, the present invention is not limited to this particular form.

Theory of Operation (0100)-(0600) Conventional Fastener Temperature Expansion Characteristics (0100)-(0300)

FIG. 1 (0100)-FIG. 2 (0200) depicts a simple non-thermally compensated fastener system comprising a bolt (0110, 0210, 0310), plate (0120, 0220, 0320), and nut (0130, 0230, 0330) and will be used to describe issues relating to the temperature variance of a typical fastener system. From FIG. 2 (0200) it can be seen that for the bolt (0110, 0210, 0310) and nut (0130, 0230, 0330) to engage and capture the plate (0120, 0220, 0320), the engaged length (0211) of the bolt (0210) must be equal to that of the engaged thickness (0221) of the plate (0220). This mating process generally occurs at a common ambient mating temperature (AMT).

However, this condition may change as temperature is increased or decreased from the AMT. For example, as generally depicted in FIG. 3 (0300) if the bolt's (0310) coefficient of thermal expansion is larger than the plate's (0320) coefficient of thermal expansion, the bolt (0310) may expand in length (0311) more than the plate (0320) expands (0321) with increasing temperature. Alternatively, if the bolt's (0310) coefficient of thermal expansion is smaller than the plate's (0320) coefficient of thermal expansion, the bolt (0310) may shrink in length (0311) less than the plate (0320) shrinks (0321) with decreasing temperature. Thus the bolt (0310)/nut (0330) combination may lose mating force with the plate (0320), causing bolt (0310) mating gaps (0322) and or nut (0330) mating gaps (0323) and a possible mechanical failure in the overall fastener system functionality.

While this example shows the bolt (0310) expanding more (0311) than the plate (0320) during heating or the bolt (0310) contracting less (0311) than the plate (0320) during cooling (0321), the opposite may also be true in which the bolt (0310) expands less than the plate (0320) during heating or the bolt (0310) contracts more (0311) than the plate (0320) during cooling in which the bolt (0310)/nut (0330) combination will exert additional force on the plate (0320) to the point that the bolt (0310)/nut (0330) combination and/or the plate (0320) may suffer deformation and/or catastrophic failure due to the increased force applied by the mismatch between the plate (0320) and the bolt (0310)/nut (0330) combination.

A common example found in industry would include a bolt (0310)/nut (0330) combination comprising mild steel having a fractional thermal expansion coefficient characteristic of 13×10⁻⁶/° C. used in conjunction with a plate (0320) comprising aluminum having a fractional thermal expansion coefficient characteristic of 24×10⁻⁶/° C. In this situation the bolt (0310)/nut (0330) combination and plate (0320) will experience a differential thermal expansion coefficient characteristic of 11×10⁻⁶/° C. The steel bolt (0310) may be stretched or the aluminum plate (0320) may severely deform as temperatures are increased beyond the AMT. If the temperatures are decreased significantly from the AMT, the aluminum plate (0320) will shrink at a greater rate than that of the steel bolt (0310)/nut (0330) combination, and thus bolt (0310)/plate (0320) and/or nut (0330)/plate (0320) slipping of the joint or even gaps (0322, 0323) may occur as generally depicted in FIG. 3 (0300).

Thermally Stabilized Fastener Temperature Expansion Characteristics (0400)-(0600)

FIG. 4 (0400)-FIG. 6 (0600) depict a simple thermally compensated fastener system comprising a bolt (0410, 0510, 0610), plate (420, 0520, 0620), nut (0430, 0530, 0630) and thermally compensating washer (0440, 0540, 0640). FIG. 4 (0400) and FIG. 5 (0500) depict the thermally compensated fastener combination in an AMT state where the bolt distance (0511) matches the combination of the plate thickness (0521) plus the thermally compensating washer (0540) thickness (0541).

Referencing the section views of FIG. 6 (0600) where the AMT has been changed such that the plate thickness (0621) has increased and the washer thickness (641) has decreased to compensate for the difference in coefficient of thermal expansion between the bolt (0610) and the plate (0620) so as to maintain a constant force on the plate (0620) through the washer (0640) by the bolt (0610)/nut (0630) combination.

Derivation of Thermally Stabilized Fastener Sizing

The two strategies used to obtain a constant clamping force with a change in temperature to produce a thermally stabilized fastener (TSF) are: (1) hold the CTE of the temperature compensating member (TCM) constant and calculate the required thickness TCM thickness (2) hold the thickness of the TCM constant and calculate the required TCM CTE. The first approach is outlined generally in SAE AIR1754B Aerospace Information Report for “Washer, Thermal Compensating, Metric Series” whereas the second approach is novel due to the unique ability to control the thermal expansion of tailored thermal expansion alloys. The specific thickness and CTE values are dependent on the thickness of the members in the mechanical member stack (MMS) and the length of the fastener (FAS) which are derived from mechanical analysis of the fastener assembly using traditional engineering design. The general expression for the mechanical and thermal displacements experienced by a thermally stabilized fastener (TSF) assembly will be derived and the two special cases for determining the TCM thickness or CTE will be presented.

The change in length of a TSF assembly with any number (n) of mechanical stacking members (MMS) can be expressed the following equation: ΔL _(FAS) ^(Thermal) +ΔL _(FAS) ^(Mechanical)=(ΔL _(TCM) +ΔL _(FRM) +ΔL _(SRM) + . . . +ΔL _(nRM))^(Thermal)+(ΔL _(TCM) +ΔL _(FRM) +ΔL _(SRM) + . . . +ΔL _(nRM))^(Mechanical)   (1)

Where ΔL is the change in length due to thermal expansion or mechanical forces, FAS is the fastener, TCM is the thermal compensating member, FRM is the 1^(st) retention member, SRM is the 2^(nd) retention member, and nRM is the n^(th) retention member where n is the number of retention members in the mechanical member stack (MMS). The change in length due to thermal expansion and changes in mechanical force can be expressed as:

$\begin{matrix} {{\Delta L^{Thermal}} = {\alpha L^{0}\Delta T}} & (2) \end{matrix}$ $\begin{matrix} {{\Delta L^{Mechanical}} = \frac{\Delta FL^{0}}{EA}} & (3) \end{matrix}$

Where α is the material's coefficient of thermal expansion (CTE), L⁰ is the original length of the member at room temperature, ΔT is the change in temperature, ΔF is the change in mechanical force, E is the material's elastic modulus, and A is the crossectional area of part that experiences the mechanical force. Substituting equations 2 and 3 into equation 1 and noticing that any change in force on the FAS is opposite and equal to a change in force on the MMS: ΔF _(FAS) =−ΔF _(TMC) =−ΔF _(FRM) =−ΔF _(SRM) =−ΔF _(nRM) =ΔF   (4) we obtain an expression for the change in force of the form:

$\begin{matrix} {{\Delta F} = {\Delta T\frac{\begin{matrix} \left( {{\alpha_{TCM}L_{TCM}^{0}} + {\alpha_{FRM}L_{FRM}^{0}} + {\alpha_{SRM}L_{SRM}^{0}} + \ldots +} \right. \\ \left. {{\alpha_{nRM}L_{nRM}^{0}} - {\alpha_{FAS}L_{FAS}^{0}}} \right) \end{matrix}}{\begin{matrix} \left( {\frac{L_{FAS}^{0}}{A_{FAS}E_{FAS}} + \frac{L_{TCM}^{0}}{A_{TCM}E_{TCM}} + \frac{L_{FRM}^{0}}{A_{FRM}E_{FRM}} +} \right. \\ \left. {\frac{L_{SRM}^{0}}{A_{SRM}E_{SRM}} + \ldots + \frac{L_{nRM}^{0}}{A_{nRM}E_{nRM}}} \right) \end{matrix}}}} & (5) \end{matrix}$

This expression can be used to calculate the desired mechanical, thermal, and dimensional characteristics of the various parts of a fastener assembly to obtain a desired temperature force profile (TFP). A simplified case is when the desired TFP is zero as the temperature changes. To obtain no change in force, ΔF=0, with changes in temperature, ΔT, equation 5 simplifies to: α_(FAS) L _(FAS) ⁰=α_(TMC) L _(TMC) ⁰ +α _(FRM) L _(FRM) ⁰+α_(SRM) L _(SRM) ⁰+ . . . +α_(nRM) L _(nRM) ⁰   (6)

Substituting the dependence of the FAS length, L_(FAS) ⁰, to the total MMS thickness: L _(FAS) ⁰ =L _(TCM) ⁰ +L _(FRM) ⁰ +L _(SRM) ⁰ + . . . +L _(nRM)   (7) into equation 6, we obtain the general expression for creating a TSF system that does not change clamping force with changing temperature: L _(TCM) ⁰(α_(TCM)−α_(FAS))=L _(FRM) ⁰(α_(FAS)−α_(FRM))+L _(SRM) ⁰(α_(FAS)−α_(SRM))+ . . . +L _(nRM) ⁰(α_(FAS)−α_(nRM))   (8)

To calculate the required thickness of a TCM of a specific CTE, equation 8 is arranged into the following form:

$\begin{matrix} {L_{TCM}^{0} = \frac{\begin{matrix} {{L_{FRM}^{0}\left( {\alpha_{FAS} - \alpha_{FRM}} \right)} + {L_{SRM}^{0}\left( {\alpha_{FAS} - \alpha_{SRM}} \right)} + \ldots +} \\ {L_{nRM}^{0}\left( {\alpha_{FAS} - \alpha_{nRM}} \right)} \end{matrix}}{\left( {\alpha_{TCM} - \alpha_{FAS}} \right)}} & (9) \end{matrix}$ where everything on the right hand side of the equation is known. This formula is very similar to equation 1 for two mechanical members in the SAE AIR1754B Aerospace Information Report for “Washer, Thermal Compensating, Metric Series”. The SAE standard is limited to only two members, called flanges in SAE AIR1754B, whereas equation 9 herein is generalized to any number, n, of mechanical members. Additionally, the SAE standard is limited to materials with known and unchangeable CTE values which is different for materials with tailored thermal expansion coefficients.

To calculate the required CTE of a TCM with a specific thickness, equation 8 is rearranged into the following form:

$\begin{matrix} {\alpha_{TCM} = {\alpha_{FAS} + \frac{\begin{matrix} {{L_{FRM}^{0}\left( {\alpha_{FAS} - \alpha_{FRM}} \right)} +} \\ {{L_{SRM}^{0}\left( {\alpha_{FAS} - \alpha_{SRM}} \right)} + \ldots +} \\ {L_{nRM}^{0}\left( {\alpha_{FAS} - \alpha_{nRM}} \right)} \end{matrix}}{L_{TCM}^{0}}}} & (10) \end{matrix}$

The unique ability to tailor the thermal expansion opens the door for engineers to design fastener systems with this equation for the first time.

These general equations can be applied to any form of mechanical affixation where mechanical force must remain constant across temperature changes including but not limited to traditional fasteners that go through holes in the members to be clamped, such as bolts and rivets, and stack ups that are inside an internally threaded tube that houses members to be clamped with a retaining ring that engages the tube's threads.

FIG. 7 (0700) illustrates a thermal expansion vs. thermal conductivity graph depicting various materials and their coefficients of thermal expansion with a particular emphasis on depicting the range of coefficients of expansion (COE) of tailored thermal expansion coefficient (TEC) (0710) materials. It is instructive to note that the TEC materials (0710) depicted can include a range of negative temperature coefficients not possible using traditional material, including most metals. This ability to provide significant negative tailored thermal coefficients of expansion allow the TEC (0710) materials utilize with the present invention to thermally stabilize a wide range of materials and metals that were heretofore not possible to thermally stabilize in a deterministic manner.

Thermally Stabilized Fastener Method (0800)

The present invention may implement a method in which a thermally stabilized fastener is designed using TEC materials fabricated to compensate a FAS/FRR/MMS combination. In this thermally stabilized fastener methodology, as generally depicted in FIG. 8 (0800), the present invention may be broadly generalized as a thermally stabilized fastener (TSF) method comprising:

-   -   (1) Selecting a fastener (FAS) type and size (this may occur         from one or more FAS databases (0810) using engineering design         principles common to fastener selection and design) (0801);     -   (2) Selecting a fastener retention receiver (FRR) type and size         (this may occur from one or more FRR databases (0820)) (0802);     -   (3) Selecting the mechanical member stack (MMS) retention         member(s) and thickness(es) (this may occur from one or more         material databases describing the materials in the MMS (0830))         (0803);     -   (4) Determining a thermal expansion rate (TER) for a combined         thermal expansion differential for the FAS, the FRR, and the MMS         (information for this calculation may occur from one or more         FAS, FRR, and MMS databases (0810, 0820, 0830)) (0804);     -   (5) Selecting a tailored CTE material with a compensating         coefficient of expansion to compensate for the TER of the         combination of the FAS, the FRR, and the MMS (this selection may         be defined in a CTE material database (0840)) (0805);     -   (6) Determining the TCM thickness requirements for a desired         mechanical load across a desired temperature range (0806);     -   (7) Fabricating the tailored CTE material to a desired form and         thickness for insertion in the MMS (0807);     -   (8) Placing the fabricated CTE material in the MMS (0808); and     -   (9) Securing the CTE material and the MMS combination using the         FAS and the FRR (0809).         This general method may be modified heavily depending on a         number of factors, with rearrangement and/or addition/deletion         of steps anticipated by the scope of the present invention.         Integration of this and other preferred exemplary embodiment         methods in conjunction with a variety of preferred exemplary         embodiment systems described herein is anticipated by the         overall scope of the present invention.

This SRH (7393) deformation may take many forms that are well known to those skilled in the art, including but not limited to spread head and flat head formations.

TCM TSF Pop Rivet System Overview (8100)-(8800)

A TCM TSF configuration utilizing a pop rivet fastener is generally depicted in FIG. 81 (8100)-FIG. 88 (8800). Here it can be seen that the fastener (7310) comprises a flat head pop rivet that constrains the MMS comprising the temperature compensating member (TCM) (8120, 8220, 8320), first retention member (FRM) (8130, 8230, 8330), and second retention member (SRM) (8140, 8240, 8340). The FRR (8150) is merged (8193, 8293, 8393) with the FAS (8110) by use of mechanical deformation of the FRT (8113) to form a secondary rivet head (SRH) (8193, 8293, 8393) in the form of a pop rivet shaft (8194, 8294, 8394) spread rivet head.

TCM TSF Tubular Fastener System Overview (8900)-(9600)

As generally depicted in FIG. 89 (8900)-FIG. 96 (9600), the present invention may be applied to situations where the fastener is in a tubular rod form such that the FRR engages the tubular rod surface internally. In this situation, the TSF is thermally stabilized via use of TSM spacers within the interior of the tube. Referencing the detail section view of FIG. 91 (9100) that describes a three-member MMS, it can be seen that in this example the MMS comprises three lenses (9131, 9132, 9133) that are retained by the FRH (9111), FRB (9112), and FRR (9150). TCM elements (9121, 9122) serve as thermal spacer elements to achieve the desired thermal compensation for the MMS to both define the force on these elements but also their relative position within the fastener (FAS) (9110) tube body, thus thermally stabilizing the optical pathway along the longitudinal optical axis of the lenses. In this example the FRR (9150) contains male threads that engage within the tubular interior of the FAS (9110), but other forms of attachment are also possible and well within the skill of one practiced in the art.

With any of the thermally stabilized fastener configurations shown in FIG. 9 (0900)-FIG. 96 (9600), the fastener (FAS) as indicated in the diagrams may incorporate a thermally compensated material such that the TCM component as shown may be augmented by a thermal characteristic in the fastener (FAS) or replaced by a fastener (FAS) having a compensating thermal characteristic such that the fastener (FAS) acts as the TCM in the overall MMS.

CONCLUSION

A thermally stabilized fastener system and method has been disclosed. The disclosed system/method integrates a fastener (FAS) incorporating a faster retention head (FRH), fastener retention body (FRB), and fastener retention tip (FRT) to couple a mechanical member stack (MMS) in a thermally stabilized fashion using a fastener retention receiver (FRR). The MMS includes a temperature compensating member (TCM), a first retention member (FRM), and an optional second retention member (SRM). The TCM is constructed using a tailored thermal expansion coefficient (TTC) that permits the TCM to compensate for the thermal expansion characteristics of the FAS, FRM, and SRM such that the force applied by the FRH and FRR portions of the FAS to the MMS is tailored to a specific temperature force profile (TFP) over changes in MMS/FAS temperature. The TCM may be selected with a TTC to achieve a uniform TFP over changes in MMS/FAS temperature.
